COLLAR- STUFFING MACHINE.

SPECIFICATION forming part of Letters Patent No. 397,292, dated February5, 1889.

Application filed April 25, 1888.

To all whom it may concern.-

Beit known that I, GEORGE E. l'IOY'l, of the city and county of SanFrancisco, State of California, have invented an Improvement inOollar-Stnliing Machines; and I hereby declare the following to be afull, clear, and exact description of the same.

Myinvention relates to a machine for studing straw into horse-collars;and my inven-' into which the straw or material usually employed for stufiinghorse-eollars is placed. The lower end or apex of this hopper has atube, B, connected with it, of sufficient size and length so that aleather tube, 0, which is to form thecollar, may be slipped over thetube B until the lower end of the tube 13 discharges into the lowerclosed end of the-collar-tube. The collar-tube O is held in place uponthe tube B by means of a hook, D, the cord E, passing over the pulley F,and a coui'iter-weight, G, or an equivalent spring, by which the leathertube is held up with sufficient power to prevent its slipping down; butas the straw is packed into it this tube is gradually forced off thetube B, so that the packing continues regularly from the bottom untilthe collartube is full. In order to pack the straw into the collar-tube,I employ a spirally-twisted auger, H, made of irregular diameter, theportion of the spiral near the bottom of the cone being of the largestdiameter, and thus tapering with a longer twist toward the bottom.

The upper end of the auger-shank is made triangular or other suitableshape, so that where itpasses through the bew el-piuion I, which givesit the rotary motion, it may also be moved vertically, sliding withinthis pinion, by meansof a crank, (shown. at J.)

In order to allow the crank to turn and convert this rotary motion intoa reciprocal mo tion of the screw-plunger, the crank-pin J $erial No.271,844. (No model.)

turns in a box,K,which slides transversely in a slotted head, L.

The upper end of the auger-shank, after passing through the bevel-gearI, is secured in the lower part of the head L, as shown at N, or in anyother suitable manner. The head L slides vertically in guides N, whichare connected in any suitable manner with the vertical standard 0,rising from the top of the hopper Upon the top of the standards O arejournal-boxes, 'within which the shaftP turns. This shaft has fixed uponit a bevel gear-wheel, Q, which engages with the bevel-gear I, and powerbeing applied to the outer end of the shaft P, either by cranks,pulleys, or in other suitable manner, the screwplunger H will be causedto rotate by the gearwheels Q and I, and it will also receiveavertically-reciprocating motion at the same time by the action of thecrank J and its intermediate guide mechanism, previously described. Inorder to guide and steady the shank of the screw or auger H, it passesthrough the bar R, which extends across the top of the hopper, and it isthus guided at that point. The auger-shank is jointed at H, so that thelower part may be removed or replaced without disturbing the upperportion.

S is aframe, made of steel or iron and having downwardly-proj ectingarms T at the cor ners. Upon each side of the frame S are trunnions U,by which the device is journaled in the sides of the hopper, so that itlies within the straw or material contained within the hopper. From oneside of the frame S a rod, D, extends upwardly to the eccentric IV,which is fixed upon the shaft E, and by this means an oscillating motionis given to the frame S and these downwardly-projecting arms T, so thatthe latter will stir or loosen up the straw and keep it from becomingpacked and stationary within the hopper. The larger portion of the augerH carries the straw downward into the tube B, and the rotary andVertical movements of the extension into the tube B will pack the strawvery firmly into the leather tube which is to form the collar,commencing at the bottom of the tube, and as the straw is packed thetube is gradually forced off the extension .13, raising the weight G,until the collar-tube is filled.

Having thus described my invention, what I tarymotien of the anger isproduced, in combii'iatien with the head L, to which the upper 1' 5 endef the auger-shank is conneetedflhe guides N, within which the headslides, and the hex K, in which the crank J turns, said hex slidingtranswn'se'ly in the head L, suhstantialLv as herein described.

In witness whereof I have IHHGUHI'U set my hand.
